Seamless Migration: GBase Database Reliably Underpins the Critical System of a Smart Toll Station on a Highway in Southwest China

Published on 2025-11-11

How can the migration of a high-speed smart toll station system be achieved without affecting the "instant gate lifting" for ETC vehicles, ensuring a seamless and "imperceptible" transition? Faced with this challenge, GBase database delivers a solution that is fast, stable, and precise, leveraging its high degree of automation and full-stack China-developed technology capabilities.

The High Demands of Smart Toll Station Migration

A highway in Southwest China, a key transportation hub in the Chengdu-Chongqing economic circle, required the migration to support smart toll collection robots, ETC special-case auxiliary equipment, and cloud-based toll collection systems across all scenarios. The migration involved 407 business tables, 12 custom views, 91 triggers from the SQL Server source database, and over 300GB of full data synchronization.

More importantly, the customer explicitly required that the stability, functionality, and performance of the database after migration match those of comparable foreign products. Any migration issues would directly impact lane throughput efficiency, causing traffic congestion and complaints from drivers and passengers.

A "Fast, Accurate, and Stable" Migration Solution 

To meet the customer's requirements, GBase 8s provided a precise solution:

  • Automated Migration Adaptation, Significantly Reducing Labor Costs

Leveraging the dedicated GBase 8s MTK automated migration tool, the entire process was automatically adapted with no need for manual modification of trigger code. Data export and loading were completed with a single click, effectively avoiding the inefficiency and error risks associated with manual adaptation.

  • Precise Control of the Migration Window, Ensuring Business Transparency

The migration was conducted during off-peak traffic periods, with the entire process from full backup to data validation completed within a few hours. After migration, the "instant gate lifting" service for ETC vehicles remained unaffected. For non-ETC vehicles, the entry card issuance time was ≤5 seconds (a 10% efficiency improvement over manual issuance), and the exit toll collection time was ≤15 seconds (a 30% efficiency improvement), with no impact on the driving experience.

  • Dual Assurance of Performance and China-Developed Technology, Supporting Long-Term Operations

GBase 8s delivers outstanding performance: it supports 5,000+ concurrent connections to handle multi-lane simultaneous toll transactions without system lag; query response time for one million records is ≤1 second, ensuring real-time retrieval of vehicle information without delay; and it supports large file storage up to 4TB, providing ample room for future smart feature expansion.

At the same time, the smart cloud warehouse is 100% China-developed, from servers and operating systems to the GBase 8s database. This not only effectively defends against external network security threats, but also reduces toll collection staff from 20 to 12 (with a plan to further optimize to 10), shifting the role from "watching the lanes" to "managing the system," significantly improving operational efficiency.

The Core of IT Application Innovation Migration: Building a "Reassuring Line of Defense" with Technical Strength 

From a provincial mobile operator's carrier-grade services to the smart toll station on a highway in Southwest China, these two cases fully demonstrate that enterprises choose GBase 8s for IT Application Innovation migration because it can effectively resolve real business pain points:

  • Strong compatibility, significantly reducing transformation costs. The highway in Southwest China achieved automated migration, and the provincial mobile operator did not need to restructure core business logic, avoiding massive manual code modification.

  • Standardized processes to ensure business continuity. Through standardized processes such as a precise migration window of a few hours and a three-phase smooth transition, core services like toll collection and communication continued uninterrupted.

  • Timely support to address migration concerns. Compatibility verification was conducted in advance, real-time technical support was provided during migration, and the post-sales team responded within hours. Compared to the remote support model of foreign databases, this response was faster and the service was more aligned with business needs.

As emphasized by the project leader of the provincial mobile operator, "True self-reliance and controllability are not about labeling, but about being able to quickly find the right person and control risks when system issues arise."

The case of the highway in Southwest China proves that IT Application Innovation migration does not necessarily bring high risks and long downtimes. With automated tools, standardized processes, and precise data validation, GBase database enabled an efficient and smooth upgrade of the core smart transportation system, providing a replicable success model for similar transportation projects.
